'I Application llled October 8. 1906. Serial No. 337887.'

'To all' whom# may concer/mf Be it known that'I, ELMER L.I OGLE, a citi-- '.j zen of the 'United States, residing at New the joints where suc York city, in the county of New York and Stateof New York, have invented new and useful Improvements in Radiators, of which -the following is aI specification.

jointed. Furthermore, the cooler is so built .f and arranged that in case of leak it may be quickly stopped by simply plugging each end of the tube.

To illustrate one form in whichI my invention may be embodied the accompanying drawings are Jfurnished which form a part hereof and in which Figure 1. represents a perspective view .of

the cooler assembled, Fig. 2. is a section of a part of the cooler showing the grouping of certain s uare tubes forming the body of the cooler. `ig. 3. is a horizontal section through a partof the cooler. Fig. 4. is a vertical section of a portion showing the delectors and a portion of the erirneter or shell. Fig. 5. is a section view s owing a construction of the deflector. Fig. 6. is a front view of one form of the cooler. Fig. 7. is a detail of the off-set lock joint in one of the tubes.-

Within the casing or shell A is secured a group of comparatively short olygonal tubes ,a through which air or other cooling medium may pass and between which the liquid to be 'cooled may circulate in thin `films and in either straight or broken' and zigzag vertical courses. To create these spaces b between the tubes a I enlarge one end of each tube and then place them side by side alternatel'y as to ends and solder these ends together; These tubes a mustl be thin and consequently fragile if they are to be ei'licient.

In my cooler do veryl little enlarging of the tubes and this at one end only coniining the enlarging to opposite, usuallytwo sides of one end only. I can thus use thinner purpose. With thinner tubes,

tubes for m ling efficiency and a lighter cooler a higher coo may be constructed which is perfectly rigid. and reliable as to construction. Y With this' arrangement it is also possible to use seamed or jointed tubes af made up of very thin copper or other ribbon, the enlargement c not necessarily coming at the joint itself.. The tubes are arranged as stated or they may be assembled in layers or rows and the row as such disposed horizontally in such manner that it is'possible to shift laterally a whole row so that all of the spaces'may come directly above the centersoi the tubes below, securing the very valuable arrangement of the vertically oli-set passages b within the body of the cooler as seen in Fig. 2. When the tubes are laid up in courses spacers may bel used as shown in Fig. 4,."9 being a plain s acer 94 aprojectingfspaeer, the projection of which may be employed as a deflector for the air. A`nller 9, (see Fig. 5.) is

provided for the o en side of the defiector.

The tubes are soli ly soldered at their ends. To produce a cooler which will withstand high ressures I 'find that this soldering shoul be .very deep and thorough, and to accomplish this I first found it necessary to tin each end of each tube.

When tubes are employed that are seamed as abovedescribed, the seam may be oil-set inwards so as to give a smooth surface on the exteriorvof1 the tube. (See Fig. 7). It can readily be seen that the tubes may be many sided or even round with squared or polygonal ends, the squared ends being preferred.

The operation of the device is evident from the foregoingdescription. Its primary use is for the rapid dissipation of heat, this being accomplished by first dividing the heated medium into thin layers'between very thin cooled walls and cause circulation in irregular courses se as to bring different portions of the medium to, be cooled into contact with such walls. The walls should be thin so.as to instantly transmit and dissipate the heat.

The casing or shell A is provided With suitable inlet and discharge openings as f and the invention extends to such use.

Having fully described my invention: l

claim .1. A cooler comprising polygonal tubes having a longitudinal seam on one flat side provided with a rectangular enlargement at one end only and grouped alternately so as to leave spaces between such tubes, substantially as described.

2. A cooler comprising square tubes having a longitudinal seam on one llat side, the seam being brought ilush on the exterior at thcends of the tube, the tubes enlarged on two opposite-unseamed sides at one end and groupe leavespaces between tially as described.

3. A cooler comprising square tubes enlarged on two opposite sides at one end and grouped alternately into rows, the rows laid suclr tubes, substanone upon the other with spacers between the ends of the tubes of eachrow.

alternately in layers or rows so as to erases s tlie ends of the tubes of each row.

In testimony whereof l have hereunto set my hand 1n presence of two subscribing w1 tnesses.
